To all whom t may concern.' l

Be it known that l, ARTHUR R. BAnNnrr, citizen of the United States,residing at Seattle, in the county of King and State of Washington, haveinvented a certain new and useful Improvement in Refrigerators, of whichthe following is a specification.

My invention relates to improvements in refrigerators, and the object ofmy inven-` tion is to provide a refrigerator which shall be adapted forhousehold use and within whose interior space the temperature may bemaintained at a much lower degree than the temperature of the externalatmosphere without the employment of ice or artificial chemical agents,whereby articles of food,y

if disposed within said refrigerator, may be kept cooler than saidexternal atmosphere,

li accomplish this object by devicesillustrated in the accompanyingdrawings wherein Figure 1 is a view of a structure embodying myinvention, in vertical section on brokenl line m, m of Fig. 3; Fig. 2 isa viewof the same in vertical section on broken line y, je/ of Fig. 1;Fig. 3 is a view of the same in horizontal section on broken line' e, zof Fig. 1; Fig. 4 is a view of'another structure, embodying a modifiedform of parts of my invention, on broken line a, a of Fig. 6; Fig. 5 isa view of the same in vertical section on broken line b of Fig. 4; Fig.6 is a view of the same inhorizontal section on broken line c, c of Fig.4; and Fig. 7 is a view in perspective of a detail of the same.Referring to the drawings, throughout which like reference numeralsindicate like parts, 8 designates an inclosing case whose interior spaceis divided-intoV two chambers 9 and ,10by a vertical partition 11 thatis lso disposed to extend Ibetween the bottom wall 12 and the top wall13 of said case 8 that,

the chamber 10 is almostfour times as large as the chamber 9, saidchamber 10 being adapted to serve as a receptacle for articles of foodthat are to be kept cool;

"Within the larger chamber 10 is a conduit 14 forwater, of rectangularcross-section, of such width as adapts it to extend throughT out thedistance betweenthe vertical front wall 15 and the vertical back wall16, and

of such length as adapts itvto extend from the lower end portion of thepartition 11 to the upper end portion thereof in a staggered coursebetween said partition 11 and the vertical side wall 17, whereby areformed three horizontal shelves 18, 19 and 20, as

shown more clearly in Fig. 1, upon whichv shelves food may be stored.

The under wall, of that portion of the conduit `14 that formsthehorizontal shelf v 18 declines from the partition 11 to the verticalside wall 17 and the under wall of that heat, shall always have aninclined path through said conduit 14 from that point that is adjacentto the bottom end portion of the vertical side wall 17 to that point ofit that is adjacent to the top end portion of the partition 11., Theunder wall of that portion of said conduit 14 that forms theY shelf 18is declined from the partition 11 in order that the whole of saidconduit 14 and its associated parts may be wholly emptied and drained,as may berequired, by turning the handle of a faucet 21 whose nipple isconnected with said conduit 14 at a point adjacent to the bottom wall 12to extend outwardly through the vertical side wall 17 as` shown.

In the lower portion of the chamber 9 are a plurality of headers 22whose nipples extend through the partition 11 vvto connect with thelower end of the conduit 14, while in the top portion of said chamber9is a like number of headers 23`whose nipples extend throught thepartition 11v to connect with the upper end of said conduit 14inpositions corresponding to the positions of the headers 22 inthebottom'portion of the chamber 9.

Each of the headers 22 is provided with two upwardlyprojecting flangedsockets, as sockets 24, and each ofthe headers 23 is provided with twodownwardly projecting flanged sockets 25,`and disposed to extendvertically between each of corresponding onesof the sockets 22 and 23 is`a conduit` lof porous material, as conduits'26, all of said verticallydisposed porous conduits 26 and the conduit 14. j

Extending downwardly from the chamber 9 through the bottom wall 12 are aplurality of air holes 27 `and extending upwardly from said chamber 9through the top wall.13 are a plurality of other air holes 28, wherebyair may enter the bottom of said chamber 9 to rise upwardly therethroughand flow outwardly from the top thereof or vice versa.

Upon the top wall 13 of the case 8, near the back wall 16 thereof, is afunnel '29 which is provided with a removable cover 30, the nippleofwhich funnel 29 projects downwardly through the top wall 13 to conn ectwith the conduit 14, through which funnel 29 water may be poured in theoper-` ation of filling the conduit 14 and ciated porous conduits 26.

The vertical front wall 15, of the case 8, is provided with a door 31which may be opened to gain access to the interior: to the largerchamber 10.

The conduit 14 and headers 22 and 23 may the assobe made of sheet metal,as galvanized sheet iron, or they may be made of molded pottery as maybe desired, and for some conditions of use they may be made of castiron; but the vertically disposed conduits 26 must be made of porousmaterial, as porous earthen ware, coarse vulcanized wood fiber, paperber or the like, so that water may percolate through the walls thereofto moisten their .exterior surfaces.

In Figs. 4, 5, 6 and 7, I have illustrated a modified form of internalparts of a re' frigerator embodying my invention wherein the largerchamber 32 (which corresponds j lrefrigerator shown in Flgs. 4, 5 and 61s to the larger chamber' 10 of Figs. 1 and 3) is provided with aconduit made of an iron pipe 33 which is formed and disposed to eX- tendfrom the lower portion of the smaller chamber 34 (which corresponds tothe smaller chamber 9 of Figs. 1 and 3) through a partitiorr35, thenceadjacent to the vertica wall 36 in a decline to a point adjacent to thevertical side wall 37 where it connects with a T fitting 38, to oneterminal of which is connected a draining faucet 39 (which correspondsto the faucet 21 of Figs. 1 and 3) vfrom which T fitting 38 said pipe 33extends on an incline to stagger back and forth and upwardly adjacent tothe vertical slde l wall 37, the vertical back wall 36 and the vmivertical partitiony 35 to the top portion of the larger chamber 32 to apoint adjacent to the partition 35 there to connect with a Tfitting-.40, to one terminal of which is connected the nipple 41 whichextends upwardly through the horizontal top'wall 42 to conneet with afunnel 43 (which corresponds tc the funnel 29 of Figs. 1 and 2), whilethe remaining terminal of the T fitting 40 connects with a nipple 44which extends through the partition 35. into the smaller chamber 34.

Within the chamber 34, at the bottom portion thereof, is a header 45 towhich is connected the bottom end of the iron vpipe 33,l

and which header 45 is provided. with a plurality of upwardly projectingsockets 46, while in the top portion of said smaller chamber 34 is aheader 47 to which is con- .nected the nipple 44 and which is providedand vertical end wall 37 at different pointsk in elevation, and uponeach pair of said rods is removably disposed a tray 53 of the form shownin Fig. 7, whose walls are perforated to form air passageways and one ofwhose sidewalls is disposed to serve as a shelf53,

as more clearly shown in Fig. 5, upon which4 front wall 54 is providedwith a door 55 f' by which one may gain access to the inter1or of thelarger chamber 32.

The smaller chamber 34, like the chamber 9 of Figs. l and 3, is providedwith air holes 56 extending through both its top and bottom wallswhereby air may flow through said chamber 34.

rllhe mode of operation of the refrigerator shown in Figs. 1, 2 and 3and that of the exactly the same and such operation may be described asfollows:

The` porous conduits in the smaller chamber and lthe non-porous 'conduitin the larger chamber are filled with water poured through the funnel ontop of the structure, which water may then soak through the walls of theporous conduits in said smaller chamber to moisten the surfaces of saidporous conduits whereupon the air that is free to circulate through saidsmaller chamber will `cause the moisture on the surfaces of' said porousconduits to evaporate, whlch process -wardly through said porous conduitagain orous l per end of said non-porous' conduit andwith vwhichembodies an inclosing case whose interior space is dvidedby a verticalpartition to form a lar er chamber and 'a smaller chamber and whic isfurther provided with la door in its front wall which opens into saidlarger chamber; a non-porous conduit for water, of oblong crosslsection,.disposed to extendfrom the bottom ortion of said smaller chamberthrough sai vertical partition into said larger chamber and across theHoor of said lar er chamber, thence upwardly to the top o said largerchamber in a staggered course toA form a plurality of shelves therein,thence' through the top end portion of said partition into said smallerchamber; a conduit of porous material vertically disposed Vin saidsmaller chamber with its upper end connected with the upits lower endconnected with the lower end of said non-porous conduit; a funneldisposed to connect with the upper portion of said non-porous conduitthrough which was ter may be poured to fill said non-porous conduit andits associated porous conduit; a faucet -connected to the lower portionof said non-porous conduit in a position to adapt it to be operated todrain all the water from said non-porous conduit and its associatedporous conduit that may be contained therein; and passageways for airextending through both the'bottom wall and the top wall of said smallerchamber. y

2. A refrigerator of the class described comprising a casing having `avertical partition dividin the same into two chambers, a double-wal.tortuous water passageway in one chamber, a porous water passageway inthe other chamber and means arranged at the upper and lower ends of thelast' named chamber forming communication beween the water passagewaysof each cham- 3. A refrigerator of the described class comprising acasing divided into two com partments, headers having vertically alinedsockets positioned in the upper and lower ends of the casing, poroustubes positioned in the alined sockets, and a non-porous waterreceptacle communicating with the headers. f In witness whereof,r Ihereunto subscribe my name this third day of January A..
